title: [Myocarditis or subendocardial myocardial infarction: role of MRI illustrated by a case report].
abstract: A 50-year-old male patient treated with mesalazine for Crohn's disease was admitted in our unit for a chest pain, associated with nonspecific ST depression or ECG and troponin elevation. Coronarography showed minimal changes while SPECT imagery suggested a posterobasal subendocardial infarction, so that the diagnosis was unclear between ischemic disease and mesalazine-induced myocarditis. Eventually, MRI demonstrated clearly a subendocardial posterior infarction eliciting the diagnosis of mesalazine-induced myocarditis. This case report illustrates, in our opinion, that MRI is of invaluable interest in evaluating the characteristics of myocardium, and must be the cornerstone in the diagnosis of myocardial diseases.
